In most cases floaters are more annoying than actually harmful. Most people find that over time you will adapt and stop noticing that the floaters are there. A good way of moving an annoying floater is to look up and down repeatedly as this could help to move it from your vision. If you do this the vitreous will move about and could help to shift the floater to a place in your eye that isn’t as visible.
If you feel that your floaters have a marked negative effect on your sight, the only way to definitively remove them is with a surgical procedure called a vitrectomy, which removes the vitreous from the eye.
Vitrectomy involves microscopic ‘keyhole’ surgery in the eye and is performed as a day procedure. Once the vitreous is removed a thorough search for any retinal breaks is performed, and the vitreous is replaced with either air or gas. The air or gas bubble can take a minimum of two weeks to dissipate from the eye. You will be given eye drops which you must use for a month after surgery.
Once the vitreous gel including the floaters has gone, it does not grow back. The eye is able to function perfectly well without it.
